"These guys did the suncoast performance kit and trans-go shift kit build in my GMC Duramax with a 5 speed Allison transmission. They had a great turnaround speed and the price was the best out of four other shops in Houston and the surrounding areas. I looked around and researched for about two weeks, and found national transmission. they kept me up to date and asked before replacing any parts and gave me options. I would recommend them to anyone looking for a build on your transmission."

"I have been having my car serviced at National Transmission for 10 years and highly recommend their service to anyone living in the Houston Texas area. Their staff of transmission specialists are experts and what they do and area always willing to spend the time with me to explain my best service and repair options."

"My Son's Honda Civic broke down with transmission related problems (manual transmission). I had AAA tow it to National Transmission and had it evaluated. It turned out to be a clutch problem. Rudy gave me an estimate and I authorized the work. Once the clutch was removed and examined Rudy called with the cost for parts. He also discovered a broken motor mount, which he replaced. The repair costs were fair, the warranty was good and the turn around time was excellent. I would use National Transmission for future work."

"For almost 20 years we have used National Transmission for all of our personal and business vesicles. Years ago transmission problem were a regular occurrence, but thanks to Rudy and John and the advice to switch to synthetic fluids they are a thing of the past. Most of our vehicles have 150k-300k miles on them."

"I lived in the neighborhood,but never used National Transmission until my Mazda 626 transmission failed. It was in walking distance, so I took my baby/Becky/car to National Transmission and I have been a faithful, loyal customer ever since 2006. I love the customer service skills of Rudy, John and Donnie. They make you feel very special and go the extra mile to provide all needed services for your vehicle. Thank you National transmission for keeping Becky(car) and I up and running."
